DEVICE FOR FEEDING SHEETS OF TIN.

SPECIFICATION forming part of Letters Patent No. 393,082, dated November 20, 1888.

Application filed May 10, 1888. Serial No. 273.430. (No model.)

To all whom it may concern.-

Be it known that 1, CHARLES W. SLEEPER, a citizen of the United States, residing at Island Pond, in the county of Essex and State of Vermont, have invented a new and useful Device for Feeding Sheets of Tin,ofwhich the following is a specification.

My invention relates to improvements in tin-feeding mechanism,by which the tin is fed to a point beyond the feeding device and during its forward movement is prepared for soldering by having its edges rolled smooth and to the proper shape and supplied with a suitable flux. I attain these objects by means of the mechanism illustrated in the accompany? ing drawings, in which Figure 1 is a vertical central longitudinal section of the device. Fig. 2 is an end view of fluxing device. Fig. 3 is a part front view of rollers enlarged to show shapes of faces. Fig. etis a front view of device complete. Fig. 5 is a plan of the same.

My invention is composed of a bed, A, provided with slots or ways A A, two adjustable sides,AA four crimping-rolls, a aa a", a fluxing device, afl nides cl l,a sliding block, d, and crossbar d a shelf, or table, 13, and various rests and guides, which will be described in their proper places. The adjustable sides A A are secured to the bed A by means of the bolts a a, and are provided with the crimping-rolls a a a" a, secured by means of shoulder screws or pins, upon which they are free to revolve. The rolls a a have faces shaped as shown in Fig. 3, while the rolls a a have fiat faces.

The fluxing device a is secured to the adjustable side Aiand consists of a metal piece, a", with a narrow groove, a, through its entire length and opened at one end to receive the tin. The piece a is also provided with a hole at a, into which the flux is fed from an ordinary lubricator by means of the tube b. The groove (0'' is intended to hold the liquid flux by capillary attraction. are provided with rests c c, to support the ends of the sheets of tin, and guides c c c c", to facilitate the placing of the sheets of tin in the proper position to be fed forward. The shelf or table B is supported by two uprights, B 13, secured to the bed A by the bolts B B". A spring-guide, B is riveted to the shelf 13. The guides d d are secured to the bed A by The sides A A suitable screws. The sliding block d is fitted between the guides 61 d, and is provided with an ear, d", to which the necessary mechanism .for moving the same will be attached. The

crossbar d (the ends of which are shaped as shown in Fig. 1) is secured to the sliding block (1.

In operating thedevice the pieces of tin, E, to be fed are placed upon the shelf or table B. The adjustable sidesA A" are moved upon the bed A to the proper position to guide the sheets of tin as required. The sheets of tin, E, are placed (one at a time) between the adjustable sides A A, so that the ends will rest upon the rests c c and the center upon the guides (2 cl. As the sliding block (1 moves forward, the ends of the cross-bar d engage with the edge of the sheet of tin and press it forward between the rolls a a a a in passing through which all lumps and nicks are pressed smooth,and the end which passes between the rolls a a is slightly crimped, so that when formed about a cylinder it will remain close to the, sameinstead of forming atangent with its circumference. As the tin is pressed forward the end which passes between the rolls a a enters the groove 60' of the fluXing device a and is moistened upon both sides by the flux in said groove. The spring-guide B holds the sheet of tin down upon the guides d (1, so that it may be fed accurately between such working parts as are provided for further operations.

\Vhat I claim as my invcntion,and desire to secure by Patent, is-

1. The combination of the bed A,thc adjustable sides A A, the rolls a a a a, and the fluxing device a", substantially as described, and for the purpose set forth.

2. The combination, with the above'de scribed bed A, sides A A rolls a a a a, and fluxing device a", of the guides d d, the sliding block (1, and the cross-bar d,substantially as described, and for the purpose set forth.

3. The combination, with the bed A, the sides A A, rollers a a a a, and fluxing device, a, of the shelf or table B, substantially as described, and for the purpose set forth.
